    Modifier and Type
    Method
    Description
    static io.micrometer.core.instrument.Counter
    counter(io.micrometer.core.instrument.MeterRegistry registry, MeterInfo meterInfo, io.micrometer.core.instrument.Tags tags)
    Returns the Counter associated with meterInfo and tags, creating it when absent.
    static io.micrometer.core.instrument.Gauge
    gauge(io.micrometer.core.instrument.MeterRegistry registry, MeterInfo meterInfo, io.micrometer.core.instrument.Tags tags, String unit, Supplier<Number> n)
    Returns the Gauge associated with meterInfo and tags, creating one bound to n when absent.
    static void
    remove(io.micrometer.core.instrument.MeterRegistry registry, io.micrometer.core.instrument.Meter... meters)
    Removes the supplied meters from the registry, skipping null entries.
    static io.micrometer.core.instrument.Timer
    timer(io.micrometer.core.instrument.MeterRegistry registry, MeterInfo meterInfo, io.micrometer.core.instrument.Tags tags)
    Returns the Timer associated with meterInfo and tags, creating it (with histogram and 50/95 percentiles) when absent.
    static io.micrometer.core.instrument.Counter
    updateCounter(io.micrometer.core.instrument.MeterRegistry registry, String meterName, io.micrometer.core.instrument.Tags tags, String description)
    Registers (or updates) a freely-named Counter, bypassing the MeterInfo catalog.
    static io.micrometer.core.instrument.Counter
    updateCounter(io.micrometer.core.instrument.MeterRegistry registry, MeterInfo meterInfo, io.micrometer.core.instrument.Tags tags)
    Registers (or updates) the Counter identified by meterInfo.
